Hartl-Dengl-Weinberger 2

Image Description and Details :

This extremely faint planetary nebula was first discovered by an American astronomer Stewart Sharpless in 1959. He included it in his catalogue of HII regions with an identification Sh2-200. Later in 1983 it was included in the HDW catalogue of possible planetary nebulae by the astronomers Herbert Hartl, Johann Dengel and Ronald Weinberger. In 2017 spectra of this object was taken by other professional astronomers and this verified their observations, confirming that this was indeed a planetary nebula.Data is acquired from my own remote observatory in central Finland using SkyWatcher Esprit 100mm f/5.5, ZWO ASI1600MM-C, EQ6 guided with ASI224MC as finder-guider, Baader narrowband filters and TS Optics RGB filters.Ha: 36x300s, OIII 120x300s, R/G/B 10x120s each.
